Hello,

We want to get the event of DoubleFeed and PaperJam when the scanner found that it feeds two more papers or it get a paper jam. How can we let the scanner send these event to us?

We found that Applications can set CAP_DEVICEEVENT to let scanner send these events back in the TWAIN Spec. How can we set CAP_DEVICEEVENT?

These features is very important for us, because we want to let users have a very good experience in the scanning process.

Could you please help us ?

Thank you very much

Hi Ericguo,

Thanks for the information.

Please check if ErrorCode and ErrorString helps.

Regards,

Hi,

We already check the errorCode and errorString. These are not working for the case. Because the scanner don't send back the event of paper jam, application cannot receive the paper jam condition.

Is there any way to let the scanner send back the event of paper jam to application?

Hi Vincy,

We already check the guide. There isn't any clues for the events.

Hi Ericguo,

Thanks for getting back to me.

To capability negotiation, it's not an event but a capability called CAP_DEVICEEVENT. I think the TW_ARRAY part of the guide will help.

Regards,
